Abstract

See full text

The invention relates to polymer compositions with improved manageability. The invention also relates to a polymer composition obtainable by radical polymerisation of A) 95-40 wt. % of a monomer mixture comprising Ai) 65-98 wt. % of at least alkyl (meth)acrylate having a linear C16-C40 alkyl radical and Aii) 2-35 wt. % of at least one comonomer selected from (meth)acrylates and (meth)acrylamides, which supports an optionally substituted aromatic radical bonded via an alkylene, alkenylene, oxyalkylene or polyoxyalkylene group to the ester group of the (meth)acrylate or to the amide group of the (meth)acrylamide, in the presence of B) 5-60% by weight % of at least one ethylene copolymer. The invention further relates to a method for the preparation and use thereof as flow improvers for paraffin-containing hydrocarbon oils.
